Again, if feasible at least a comparison in percentage regarding start up cost, life cycle cost such as maintenance and cost for disposal might be helpful ...

hi Benny,
Air storage vessel size to vary for small or larger applications.
Itemized see below cost.
1. Air motor 10 HP $600 US.
2. Standard 7.5 kw generator motor $985 US. (marathon motors USA).
3. Air vessel in metal or concrete underground by local labour
and materials approx $3000 US.
4. Air compressor two stage $1300 US.
5. Misc connections (wiring, air tubing, fittings etc.) $300 US.
TOTAL COST $6,185 US.
All the above components have, with proper maintenance, 10 years
lifetime or more. As a result the yearly cost is $618 US.
The performance of this storage arrangement is:
a. Complete stand alone home.
b. All electrical devices are powered 100%.
c. Power supply for 3-4 days depending on consumption.
d. More time to play, less to worry about battery charge levels.
e. Enviro friendly.
f. 100% reliable. The ice will never melt in the fridge.
I believe this air storage system may even cost less than batteries
on the long run. Your friends will love it as much as you when
you invite them for dinner. They would be very interested to
see how you have power all the time and they do not.
Hope you agree, talk to you again soon.
